function xwdwrite(M,CM,fname)
%XWDWRITE  Write a XWD (X window dump) file to disk.
%   Note: XWDWRITE has been grandfathered; use IMWRITE instead.
%
%   XWDWRITE(X,MAP,'filename') writes an XWD file containing the
%   indexed image X and colormap MAP to a disk file called 'filename'.
%   Valid range for elements of X is from 1 to the number of entries
%   in the colormap.
%
%   The extension '.xwd' will be added to 'filename' if it doesn't
%   already have an extension.

%   See also IMFINFO, IMREAD, IMWRITE.
